3Blue1Brown on Wordle, probability, information theory, and expected value.

Whether or not you've been sucked into this word game fad, this is a really good explanation of the relationships between probability and expected information value (I = -log2(p)), as well as how to optimally find one element within a known search space.
It explains the logic behind selecting starting words for Wordle, as well as how and why optimisers choose their own guesses, and what an optimal solver's ultimate limits would be.
